Development and psychometric validation of PUKAT 2·0, a knowledge assessment tool for pressure ulcer prevention.

The aim of this study was to develop a tool to measure the knowledge of nurses on pressure ulcer prevention. PUKAT 2·0 is a revised and updated version of the Pressure Ulcer Knowledge Assessment Tool (PUKAT) developed in 2010 at Ghent University, Belgium. The updated version was developed using state-of-the-art techniques to establish evidence concerning validity and reliability. Face and content validity were determined through a Delphi procedure including both experts from the European Pressure Ulcer Advisory Panel (EPUAP) and the National Pressure Ulcer Advisory Panel (NPUAP) (n = 15). A subsequent psychometric evaluation of 342 nurses and nursing students evaluated the item difficulty, discriminating power and quality of the response alternatives. Furthermore, construct validity was established through a test-retest procedure and the known-groups technique. The content validity was good and the difficulty level moderate. The discernment was found to be excellent: all groups with a (theoretically expected) higher level of expertise had a significantly higher score than the groups with a (theoretically expected) lower level of expertise. The stability of the tool is sufficient (Intraclass Correlation Coefficient = 0·69). The PUKAT 2·0 demonstrated good psychometric properties and can be used and disseminated internationally to assess knowledge about pressure ulcer prevention.

The effectiveness of three types of alternating pressure air mattresses in the prevention of pressure ulcers in Belgian hospitals.

To compare the effectiveness of multi-stage and one-stage alternating low-pressure air mattresses (ALPAM) and alternating pressure air mattress (APAM) overlays in preventing pressure ulcers among hospitalized patients, data were pooled (N = 617) from a study of patients allocated to multi-stage ALPAM (n = 252) or one-stage ALPAM (n = 264), and another study of patients allocated to APAM overlay (n = 101). Cumulative pressure ulcer incidence was 4.9% (n = 30) over 14 days. Fewer ulcers developed on multi-stage ALPAM compared with APAM overlay (OR = 0.33; 95% CI [0.11, 0.97]), but no difference was found between one-stage ALPAM and APAM overlay (OR = 0.40; 95% CI [0.14, 1.10]). Time to develop ulcers did not differ by mattress type.

Malnutrition and associated factors in nursing home residents: a cross-sectional, multi-centre study.

BACKGROUND & AIMS: Malnutrition is a common problem in the elderly living in nursing homes. A clear understanding of associated factors is missing. The aim of this study was to evaluate prevalence of malnutrition and to determine factors independently associated with malnutrition in this setting. METHODS: A cross-sectional, multi-centre study was conducted in 23 nursing homes in Flanders, Belgium. The nutritional status was assessed using the Mini Nutritional Assessment (MNA). Data on possible associated factors were collected using validated scales. RESULTS: The study included 1188 elderly residents; 38.7% were at risk for malnutrition and 19.4% were malnourished. The presence of a wound/pressure ulcer, a recent hospitalization (<3 months ago), being involved in a tailored nutritional intervention, and suffering from a lower cognitive state were significantly associated with malnutrition. Receiving additional meals provided by family members was negatively associated with malnutrition. CONCLUSION: Malnutrition is a prevalent problem in nursing homes in Flanders. Systematic screening and well-defined tailored interventions should be further developed and evaluated in this population at risk.

A multi-faceted tailored strategy to implement an electronic clinical decision support system for pressure ulcer prevention in nursing homes: a two-armed randomized controlled trial.

BACKGROUND: Frail older people admitted to nursing homes are at risk of a range of adverse outcomes, including pressure ulcers. Clinical decision support systems are believed to have the potential to improve care and to change the behaviour of healthcare professionals. OBJECTIVES: To determine whether a multi-faceted tailored strategy to implement an electronic clinical decision support system for pressure ulcer prevention improves adherence to recommendations for pressure ulcer prevention in nursing homes. DESIGN: Two-armed randomized controlled trial in a nursing home setting in Belgium. The trial consisted of a 16-week implementation intervention between February and June 2010, including one baseline, four intermediate, and one post-testing measurement. Primary outcome was the adherence to guideline-based care recommendations (in terms of allocating adequate pressure ulcer prevention in residents at risk). Secondary outcomes were the change in resident outcomes (pressure ulcer prevalence) and intermediate outcomes (knowledge and attitudes of healthcare professionals). SETTING: Random sample of 11 wards (6 experimental; 5 control) in a convenience sample of 4 nursing homes in Belgium. PARTICIPANTS: In total, 464 nursing home residents and 118 healthcare professionals participated. METHODS: The experimental arm was involved in a multi-faceted tailored implementation intervention of a clinical decision support system, including interactive education, reminders, monitoring, feedback and leadership. The control arm received a hard-copy of the pressure ulcer prevention protocol, supported by standardized 30 min group lecture. RESULTS: Patients in the intervention arm were significantly more likely to receive fully adequate pressure ulcer prevention when seated in a chair (F=16.4, P=0.003). No significant improvement was observed on pressure ulcer prevalence and knowledge of the professionals. While baseline attitude scores were comparable between both groups [exp. 74.3% vs. contr. 74.5% (P=0.92)], the mean score after the intervention was 83.5% in the experimental group vs. 72.1% in the control group (F=15.12, P<0.001). CONCLUSION: The intervention was only partially successful to improve the primary outcome. Attitudes improved significantly while the knowledge of the healthcare workers remained unsatisfactorily low. Further research should focus on the underlying reasons for these findings.

The association between malnutrition and oral health status in elderly in long-term care facilities: a systematic review.

OBJECTIVES: Malnutrition is a common problem in the elderly. It is not clear if oral health is associated to malnutrition in this population. The aim of this systematic review is to determine whether an association exists between oral health and malnutrition in the elderly in a long-term care facility. DESIGN: Systematic review. DATA SOURCE: Medline, Cochrane and Cinahl were systematically searched for to identify articles published between January 1985 and May 2011. Reference lists were checked for additional publications. REVIEW METHODS: Publications were included if they explored the association between oral health status and malnutrition. As no consensus about terminology was found, a sensitive filter was developed. The methodological quality of the studies was assessed. Two independent reviewers performed all methodological steps. RESULTS: Sixteen studies met the criteria for inclusion. Eleven studies used a multivariate approach; nine of these found an association between oral health status and malnutrition. Four studies found a relationship between masticatory problems and malnutrition. Five studies found an association between malnutrition and dental condition, number of oral problems, tongue alteration, problems with saliva flow, and candidiasis. Overall, the methodological quality of the studies was medium. CONCLUSIONS: Tentative evidence indicates an independent association between oral health status and malnutrition in the elderly residing in a long-term care facility. Caution is needed for the interpretation of these results because of the absence of a gold standard to define and assess malnutrition and oral health status and the presence of methodological limitations throughout the studies.

Pressure ulcers: knowledge and attitude of nurses and nursing assistants in Belgian nursing homes.

AIMS: To gain insight into the knowledge and attitudes of nurses and nursing assistants and to study the correlation between knowledge, attitudes and the compliance with the pressure ulcer prevention guidelines provided to residents at risk of pressure ulcers in nursing homes. BACKGROUND: There is a lack of evidence on knowledge and attitudes of nurses and nursing assistants towards pressure ulcer prevention in nursing homes. DESIGN: A cross-sectional multi-centre study. METHODS: A convenience sample of nine Belgian nursing homes, representing 18 wards was chosen in the study. In total, 145 nurses and nursing assistants were included. The compliance with the guidelines was evaluated in 615 residents, and data were collected using validated instruments. RESULTS: Fully compliant prevention was found in only 6·9% of the residents at risk. The mean knowledge score of the nurses was 29·3 vs. 28·7% for the nursing assistants. The overall attitude score was 74·5%, and attitude scores were significantly different between nurses and nursing assistants. Nurses showed to have a more positive attitude towards pressure ulcer prevention than nursing assistants, respectively 78·3 and 72·3%. A more positive attitude was a significant predictor of pressure ulcer prevention compliance with the guidelines provided to residents at risk of pressure ulcers in nursing homes. CONCLUSIONS: Knowledge about pressure ulcer prevention of both nurses and nursing assistants in nursing homes was low. Attitudes were a significant predictor of the application of fully compliant prevention in residents at risk. RELEVANCE TO CLINICAL PRACTICE: Pressure ulcer prevention is an important aspect in daily care for residents at risk in nursing homes. These insights will contribute to evidence-based practice in this area of care and will form the basis for the development of an education strategy for pressure ulcer prevention and management in nursing homes.

A 3-in-1 perineal care washcloth impregnated with dimethicone 3% versus water and pH neutral soap to prevent and treat incontinence-associated dermatitis: a randomized, controlled clinical trial.

PURPOSE: We compared the effectiveness of a 3-in-1 perineal care washcloth versus standard of care (water and pH neutral soap) to prevent and treat incontinence-associated dermatitis (IAD). The product under study was a soft, premoistened washcloth, including a 3% dimethicone formula, with cleansing, moisturizing, and barrier protection properties. DESIGN: Randomized, controlled clinical trial. SUBJECTS AND SETTING: The study sample comprised a random sample of 11 nursing home wards (6 experimental and 5 control) in a convenience sample of 4 nursing homes in Belgium. The sample included nursing home residents at risk for and/or affected by IAD defined as incontinent of urine, feces, urine/feces, and/or having erythema of the perineal skin (not caused by pressure/shear), and/or having an edematous skin in the genital area. METHODS: Participants in the experimental group were treated according to a standardized protocol, including the use of a 3-in-1 perineal care washcloth impregnated with a 3% dimethicone skin protectant. Participants in the control group received perineal skin care with water and pH neutral soap, the standard of care in Belgian nursing homes. The study period was 120 days. Data were collected between February and May 2010. Incontinence-associated dermatitis prevalence and severity were assessed using the IAD Skin Condition Assessment Tool. The surface (cm), redness, and depth of the perineal lesion were assessed daily by the nurses. This tool generates a cumulative severity score (maximum score = 10) based on area of skin affected, degree of redness, and depth of erosion. RESULTS: Four hundred sixty-four nursing home residents were assessed and 32.9% (n = 141) met the criteria for inclusion, including 73 subjects in the experimental group and 68 in the control group. Baseline IAD prevalence was comparable in both groups (experimental: 22.3% vs control: 22.8%, P = .76). Baseline IAD severity was 6.9/10 in the experimental group and 7.3/10 in the control group. A significant intervention effect on IAD prevalence was found (experimental: 8.1% vs control: 27.1%, F = 3.1, P = .003). A nonsignificant effect on IAD severity could be determined (experimental: 3.8/10 vs control: 6.9/10, F = 0.8, P = .06). CONCLUSION: The use of a 3-in-1 washcloth, impregnated with a 3% dimethicone formula, resulted in a significantly reduced prevalence of IAD and a trend toward less severe lesions. These findings provide indicative evidence for the use of 3-in-1 perineal care washcloth as an effective intervention against the use of water and a pH neutral soap to prevent and/or treat IAD.

Clinical challenges of preventing incontinence-associated dermatitis.

Incontinence-associated dermatitis (IAD) is a common skin disorder in patients with faecal and/or urinary incontinence. The past decade has seen a huge growth in publications focusing on the complexity and inconsistency of the clinical observation of IAD and the differentiation between IAD and pressure ulcers. IAD and superficial pressure ulcers cause confusion in clinical practice when trying to determine the true nature and underlying pathology of the lesion. It is a daily challenge for health professionals in hospitals, nursing homes and community care to maintain a healthy skin in patients with incontinence. The aim of this article is to provide a brief update on recent developments regarding the differentiation between pressure ulcers and IAD and the prevention of IAD. Recommendations for clinical practice and research are provided.

Non-direct patient care factors influencing nursing workload: a review of the literature.

AIMS: The aim of this paper was to detect which non-direct patient care factors are related to nursing workload in acute hospital nursing care and to develop a conceptual model to describe the relationship between the non-direct patient care factors and nursing workload. BACKGROUND: Since the 1930s, efforts to measure nursing workload have been undertaken. Still, it remains unclear which of the non-direct patient care elements are essential to the nursing workload. DATA SOURCES: PubMed, Embase, the Cumulative Index to Nursing and Allied Health Literature, Engineering Village 2, Elin and the British Nursing Index were searched from 1970 up to July 2009. REVIEW METHODS: Studies were included in this integrative review if they described factors that are related to nursing workload or if they presented models that explored the association between potential factors, excluding the factors related to direct patient care. RESULTS: Thirty publications were included. The influencing variables were classified in five categories based on their level of impact: the hospital and ward, nursing team, individual nurse, patient and family and meta-characteristics. The variables were also classified, based on their cause-effect relationship. Some factors have a direct impact on the patient-nurse relationship, while others have an effect on the work fluency or on the subjective perception of the nursing workload. A conceptual model was built, based on the interaction between both classifications and derived from the systems theory. CONCLUSIONS: Nursing workload has a multi-causal aetiology. The influencing factors from this review can be integrated in a workload measurement tool.

Knowledge and attitudes of nurses on pressure ulcer prevention: a cross-sectional multicenter study in Belgian hospitals.

BACKGROUND: Evidence-based guidelines for pressure ulcer prevention have been developed and promoted by authoritative organizations. However, nonadherence to these guidelines is frequently reported. Negative attitudes and lack of knowledge may act as barriers to using guidelines in clinical practice. AIMS: To study the knowledge and attitudes of nurses about pressure ulcer prevention in Belgian hospitals and to explore the correlation between knowledge, attitudes, and the application of adequate prevention. METHODS: A cross-sectional multicenter study was performed in a random sample of 14 Belgian hospitals, representing 207 wards. Out of that group, 94 wards were randomly selected (2105 patients). Clinical observations were performed to assess the adequacy of pressure ulcer prevention and pressure ulcer prevalence. From each participating ward, a random selection of at least five nurses completed an extensively validated knowledge and attitude instrument. In total, 553 nurses participated. A logistic regression analysis was performed to evaluate the correlation between knowledge, attitudes, and the application of adequate prevention. RESULTS: Pressure ulcer prevalence (Category I-IV) was 13.5% (284/2105). Approximately 30% (625/2105) of the patients were at risk (Bradenscore <17 and/or presence of pressure ulcer). Only 13.9% (87/625) of these patients received fully adequate prevention whilst in bed and when seated. The mean knowledge and attitude scores were 49.7% and 71.3%, respectively. The application of adequate prevention on a nursing ward was significantly correlated with the attitudes of the nurses (OR = 3.07, p = .05). No independent correlation was found between knowledge and the application of adequate prevention (OR = 0.75, p = .71). CONCLUSIONS: Knowledge of nurses in Belgian hospitals about the prevention of pressure ulcers is inadequate. The attitudes of nurses toward pressure ulcers are significantly correlated with the application of adequate prevention. No correlation was found between knowledge and the application of adequate prevention.

Assessing the adequacy of pressure ulcer prevention in hospitals: a nationwide prevalence survey.

INTRODUCTION: The development of a pressure ulcer is an adverse event and is often avoidable if adequate preventive measures are applied. No large-scale data, based on direct patient observations, are available regarding the pressure ulcer preventive interventions used in hospitals. PURPOSE: The aim of this study was to obtain insight into the adequacy of interventions used to prevent pressure ulcers in Belgian hospitals. METHODS: A cross-sectional, multi-centre pressure ulcer prevalence study was performed in Belgian hospitals. The methodology used to measure pressure ulcer prevalence was developed by the European Pressure Ulcer Advisory Panel. The data collection instrument includes five categories of data: general data, patient data, risk assessment, skin observation and prevention. RESULTS: The total sample consisted of 19,968 patients. The overall prevalence of pressure ulcers Category I-IV was 12.1%. Only 10.8% of the patients at risk received fully adequate prevention in bed and while sitting. More than 70% of the patients not at risk received some pressure ulcer prevention while lying or sitting. CONCLUSION: Generally, there is a limited use of adequate preventive interventions for pressure ulcers in hospitals, which reflects a rather low quality of preventive care. The implementation of pressure ulcer guidelines requires more attention. The pressure ulcer prevention used in practice should be re-evaluated on a regular basis.

Adherence to leg ulcer lifestyle advice: qualitative and quantitative outcomes associated with a nurse-led intervention.

AIM AND OBJECTIVES: Examining the (experienced) changes associated with a nursing intervention to enhance adherence to leg ulcer lifestyle advice. BACKGROUND: Few interventions to enhance adherence to leg ulcer treatment are developed and tested. DESIGN: Qualitative evaluation approach and pre-post-test design were used. METHOD: Twenty-six patients with venous ulcers in a community care setting participated. Data were collected by means of interviews and participant observation. Frequency and duration of wearing compression, leg exercising and leg elevation, activity level, pain and ulcer size were registered at baseline, after the end of the intervention and three months later. Inductive content analysis and Wilcoxon signed-rank test were used. RESULTS: Knowledge about leg ulcer advice increased. The education contributed to more consciously following of the advice. The rationale of the advice and its association with healing or recurrence remained often unclear. More patients performed exercises after the intervention and at follow-up. Patients often looked out onto a 'new' perspective where enhancement of quality of life and even healing might be attainable. Some patients regained independence after learning how to apply and remove compression garments themselves. The frequency of exercising and the duration of exercises increased significantly. Step counts had not altered significantly. Patients not elevating the legs at baseline elevated the legs more and for a longer period of time after the intervention. This effect on leg elevation decreased after three months. No significant changes were reported on hours wearing compression. CONCLUSIONS: The perceived changes suggest that the intervention holds a promise for current home care. Combining qualitative and quantitative research assisted to determine the possible effects of the intervention, increasing the potential for a meaningful randomised trial in the future. RELEVANCE TO CLINICAL PRACTICE: Education about leg ulcer advice should be incorporated in nursing practice. Further testing of the intervention is recommended.

Malnutrition and nutritional care practices in hospital wards for older people.

AIMS: This paper is a report of a study conducted to gain a better insight into the current nutritional care practices in Belgian hospital wards for older people, and to study the association between these practices and the prevalence of malnutrition. BACKGROUND: In 1999, the Council of Europe assessed nutritional care practices and support in 12 European countries and showed them to be sparse and inconsistent. At the time of research, no studies had described the association between nutritional care practices and malnutrition prevalence in Belgium. METHODS: In 2007, a cross-sectional survey was carried out in a representative sample of Belgian hospital wards for older people. In total, 2094 patients from 140 wards for older people were included. RESULTS: The overall prevalence rate of malnutrition in wards for older people was 31.9%. Nutritional care practices such as nutritional screening and assessment, use of a standardized screening instrument and a nutritional protocol were suboptimal. Multilevel analysis revealed that ward characteristics explained for 9.1% whether a patient was malnourished or not. None of the registered nutritional care practices could explain a patient's individual risk. CONCLUSION: Malnutrition is a frequently occurring problem on hospital wards for older people. Increased consciousness among healthcare professionals and hospital policy makers of the importance of nutritional care will contribute to further improvement in care quality.

Implementation of a guideline for pressure ulcer prevention in home care: pretest-post-test study.

AIMS AND OBJECTIVES: To investigate the effect of the implementation of a patient and family education programme for pressure ulcer prevention in an organisation for home care nursing on guideline adherence and on prevalence and severity of pressure ulcers and to examine the determining factors for the application of measures for pressure ulcer prevention. BACKGROUND: Quality improvement programmes in pressure ulcer prevention are not always successful. DESIGN: Implementation study using a pretest-post-test design. Data were collected in three probability samples. The first post-test data collection was held after six months, the second after 18 months. METHOD: Statistical analysis was used, comparing the pretest sample and the second post-test sample. RESULTS: After 18 months, the proportion of subjects with adherent measures had increased from 10·4-13·9%, the proportion of subjects with non-adherent measures decreased from 45·7-36·0%, the proportion of subjects without pressure ulcer prevention increased from 43·9-50·1% (p<0·0001, Chi-square test). Sub-analysis revealed that a positive change in guideline adherence was observed principally in the group at risk. Better process-of-care indicators were associated by lower pressure ulcer prevalence and less severe skin lesions. The nurses' judgement of a patient risk status was the most important factor for applying preventive measures. Furthermore, application of pressure ulcer prevention was determined by higher age (from the age category of 70-79 years), higher dependency for the activities of daily living, higher than baseline mobility score and the presence of a pressure ulcer. CONCLUSIONS: Guideline adherence in pressure ulcer prevention changed significantly after implementation of the education programme. There might have been inconsistencies in the nurses' risk judgement. RELEVANCE TO CLINICAL PRACTICE: Quality of pressure ulcer prevention improved, but several items for improvement remain. Adaptation of risk assessment procedures is needed.

Malnutrition and associated factors in elderly hospital patients: a Belgian cross-sectional, multi-centre study.

BACKGROUND & AIMS: In Belgium, general data on the prevalence of malnutrition are lacking. Prevalence rates are necessary to gain insight into the magnitude of malnutrition and to establish a nutrition policy that takes the limited health care resources into account. This study aimed to obtain insight into the prevalence of malnutrition in Belgian elderly hospital wards and to identify factors associated with the malnutrition prevalence. METHODS: A cross-sectional, multi-centre study in elderly wards of Belgian hospitals. The nutritional status was assessed using the Mini Nutritional Assessment. A standardised questionnaire was used to record demographic data and data on potential factors associated with malnutrition. RESULTS: Out of 2329 elderly patients, 33% suffered from malnutrition. Almost 43% of the patients were at risk of malnutrition and 24% were well-nourished. Having swallowing difficulties, taste difficulties, and being transferred from a nursing home were strongly associated with being malnourished. CONCLUSION: The malnutrition prevalence in Belgian elderly hospitals wards is similar to international figures. Elderly who have swallowing difficulties, taste difficulties, or coming from a nursing home may need adequate nutritional care. Given the negative impact of malnutrition on mortality and morbidity, an emphasis should be placed on an effective nutritional policy.

The identification of older nursing home residents vulnerable for deterioration of grade 1 pressure ulcers.

AIMS AND OBJECTIVE: The objective of this study was to identify prognostic factors associated with the development of pressure ulcer lesions (grade 2-4) in nursing home patients with non-blanchable erythema. BACKGROUND: No studies could be found that identify risk factors for further development of pressure ulcer in patients with non-blanchable erythema. For some patients with non-blanchable erythema, standard preventive measures do not suffice to prevent pressure ulcers from deterioration. Identifying these patients beforehand can considerably contribute to the efficiency of pressure ulcer prevention. DESIGN: Secondary data analyses of a previously conducted randomised controlled trial were performed. METHODS: Eighty-four wards of 16 Belgian nursing homes participated in the study. In total, 235 nursing home residents with a grade 1 pressure ulcer (non-blanchable erythema) were included. All the residents received standard preventive care. Potential prognostic factors were collected using a standardised form. The incidence of pressure ulcers was recorded according to the European pressure ulcer classification system. RESULTS: The cumulative pressure ulcer incidence was 18.7% (44/235). Hypotension (relative risk = 3.42, 95% CI = 1.56-7.49), a history of a cerebral vascular accident (relative risk = 1.94, 95% CI = 1.10-3.70) and contractures (relative risk = 2.02, 95% CI 1.03-3.95) were identified as independent predictive factors for developing pressure ulcers. Remarkably, being urinary incontinent decreased the risk of developing a pressure ulcer by 76%. CONCLUSIONS: In nursing home residents with non-blanchable erythema, hypotension, contractures, and a history of cerebral vascular accident were independent risk factors for the development of pressure ulcer lesions. RELEVANCE TO CLINICAL PRACTICE: Patients with non-blanchable erythema who have hypotension, contractures or a history of cerebral vascular accident are in need of more intensive preventive measures. Identifying these patients can contribute considerably to a more efficient pressure ulcer prevention policy, resulting in a lower pressure ulcer lesion incidence and in lower costs.

Effectiveness of two cushions in the prevention of heel pressure ulcers.

AIM: The aim of the study was to determine the effectiveness of two cushions in the prevention of heel pressure ulcers in a geriatric population. BACKGROUND: Heel pressure ulcers are a major problem in nursing practice. Several measures for the prevention of heel pressure ulcers are discussed in the literature, but the effectiveness of the different types of cushions in the prevention of heel pressure ulcers is poorly studied. METHODS: In this comparative study, two different cushions to prevent heel pressure ulcers were investigated: a wedge-shaped, bedwide, viscoelastic foam cushion and an ordinary pillow. All patients were lying on a viscoelastic foam mattress and were repositioned every 4 hours. SAMPLE: One hundred sixty-two patients over 75 years of age. RESULTS: The incidence of heel pressure ulcers grades 2-4 was 1.9% in the wedge-shaped cushion group and was 10.2% in the pillow group. The patients in the wedge-shaped cushion group developed significantly fewer heel pressure ulcers (p = 0.03). Patients with a wedge-shaped cushion under the lower legs had an 85% less chance in developing a heel pressure ulcer (p = 0.02). The median time to develop a heel pressure ulcer was 4.0 days (IQR = 3.0-5.0) in the wedge-shaped cushion group and 3.5 days (IQR = 1.0-5.8) in the pillow group (p = 0.61). The probability to remain pressure ulcer-free at the heels was significantly higher in the wedge-shaped cushion group (p = 0.008). CONCLUSION: The study provides evidence that a wedge-shaped, bedwide, viscoelastic foam cushion decreases the risk of developing a heel pressure ulcer compared with the use of a pillow.

A systematic review of the use of hydrocolloids in the treatment of pressure ulcers.

AIMS AND OBJECTIVES: The aim of this systematic literature review was to describe the current evidence in the field of pressure ulcer treatment with hydrocolloids and to give recommendations for clinical practice and further research. BACKGROUND: Pressure ulcers are a common problem in clinical practice and generate substantial expense. A wide range of dressings is available but little is known about the effect on pressure ulcer healing. METHODS: A Cochrane-based search strategy was used in four databases (PubMed, Embase, the Cochrane Central Register of Controlled Trials and the Cumulative Index to Nursing and Allied Health Literature), manuals and reference lists. Randomised controlled trials on the treatment of pressure ulcers with hydrocolloids, as defined by the British National Formulary, were systematically included and analysed. RESULTS: Twenty-nine publications, dealing with 28 different studies, met the inclusion criteria and were included in the review. Hydrocolloids were most frequently used on pressure ulcers grade 2-3. Concerning the healing of the pressure ulcer, hydrocolloids are more effective than gauze dressings for the reduction of the wound dimensions. The absorption capacity, the time needed for dressing changes, the pain during dressing changes and the side-effects were significantly in favour of hydrocolloids if compared to gauze dressings. Based on the available cost-effectiveness data, hydrocolloids seemed to be less expensive compared with collagen-, saline- and povidine-soaked gauze but more expensive compared to hydrogel, polyurethane foam and collagenase. CONCLUSIONS: This review demonstrates that hydrocolloids are to be preferred to gauze dressings in the treatment of pressure ulcers. Additional research is needed to confirm these results. RELEVANCE TO CLINICAL PRACTICE: Based on the studies included in this review, hydrocolloids are frequently used in the treatment of grade 2 and 3 pressure ulcers and are more effective and less expensive than gauze dressings. Compared with alginates, polyurethane dressings, less-contact layers, topical enzymes and biosynthetic dressings, hydrocolloids are less effective.
